Quality control problems with LCD panels from LG Display may have contributed to the prolonged shortage of the iPad 2

From TUAW:

According to the report from Digitimes, early batches of the 9.7-inch panels supplied by LG had a light leak issue that limited LG's ability to meet demand. As a result, LG only produced 3.2 million panels in the first quarter of 2011, a figure that trails the four million panels produced by Samsung. This report corroborates an earlier report from IHS iSuppli that blamed the iPad 2 shortage on an unknown manufacturing problem with LCDs.
